I was just a typical four-year-old boy named Jamie, until the day I found that peculiar artifact at daycare. It was a small, round object covered in strange symbols.

As soon as I touched it, something amazing happened. I swapped ages with my big brother, Sam. I was thrilled at first, now I could reach the cookie jar!

My joy quickly faded when my parents announced they were leaving for their date. They expected me to babysit Sam, who was now a toddler!

Sam was not happy about the situation. He sulked and cried, missing his teenage freedom. I was in over my head, struggling to keep him entertained.

I tried to reverse the swap, touching the artifact again, but nothing happened. I was stuck as a teenager, and Sam was stuck as a toddler.

Realizing that we were stuck, I decided to make the most out of it. I took Sam to the park, hoping the playground would cheer him up.

At the park, Sam started playing like a typical toddler, while I watched from the bench. It was strange to see my big brother acting like this.

After the park, I took Sam to the ice cream shop. He was delighted with the treat, but I was exhausted from all the babysitting.

Later, at home, I read Sam a bedtime story. He fell asleep, hugging his teddy bear. I felt a strange sadness seeing him like this.

I missed my carefree life as a toddler. I missed having Sam to look up to. I missed being the little brother.

The next morning, I took Sam to daycare. Seeing the kids my age, playing and laughing, made me long for my old life.

I spent the day researching about the artifact online. I learned it was an ancient relic that could only be used once per person.

I felt desperate. I needed to find someone who hadn't used the artifact yet, someone who could help us swap back.

That's when I remembered Mrs. Johnson, our elderly neighbor. She was kind and understanding, maybe she could help us.

I went to Mrs. Johnson's house and explained the situation. She listened patiently, nodding her head as I showed her the artifact.

To my surprise, Mrs. Johnson agreed to help. She held the artifact and wished for Sam and me to return to our original ages.

Suddenly, I felt a familiar sensation. I was shrinking, my clothes becoming too big for me. I was a toddler again!

I looked at Sam, who was growing taller and older. He was back to his teenage self, a relieved smile on his face.

We thanked Mrs. Johnson and ran home. Our parents were surprised to see us back to our original selves. I was just happy to be a kid again.

Sam and I had a new appreciation for each other's lives. We realized that each age had its own challenges and joys.

As for the artifact, we decided to bury it in the backyard. We didn't want anyone else to go through what we had experienced.

That night, as Sam read me a bedtime story, I felt a sense of contentment. I was happy to be the little brother again.

I learned a valuable lesson that day. Every age has its own beauty and challenges. And I was perfectly happy being four.

I fell asleep, dreaming of my big brother Sam and our incredible adventure. I was glad things were back to normal.

As for Sam, he was just happy to have his teenage life back. We both agreed to enjoy our current ages while we could.
